AUTOMOBILE STORAGE-JACK.

Specification of Letters Patent.

Application filed May 1, 1911.

Patented July 11, 1911.

Serial No. 624,429.

To all whom it may concern: I A Be it known that I, WILLIAM H. HATTEL, acitizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have invented a new and useful Automobile Storage-Jack, of which the following is a specification.

My invention relates to improvements in automobile storage jacks, in which a vertically reciprocating plunger is operated by means of a cam pivotally secured to a ver-v tically adjustable cross-head for the purpose of raising an automobile off its wheel tires, thus relieving said tires from the weight of the machine when at rest or in storage.

The objects of my invention are, first to provide jacks that are adjustable for different sizes of wheels; second, to provide a jack in which the lever actuating the raising mechanism shall operate parallel to the side of the frame and the wheel, thereby reducing the space occupied by the jack outside of the wheel to a minimum, and in which the Weight of the said lever shall lock said raising mechanism in either an up or down position; third, to provide a jack hav? ing three bearing points in its base, to insure stability on the floor and prevent liability of tipping over when bearing the weight of the automobile; fourth, to provide a jack that shall be inexpensive to manufacture, eifectual in operation and neat in appearance.

Other objects will more definitely appear in the detail description to follow.

I accomplish the objects of my invention by the devices and means described vin this specification and definitely pointed out in the claims.

Structures embodying the features of my invention are clearly illustratedV in the accompanying sheet of drawings, forming a part of this specification, in which- Figure 1 is a side elevation of my improved jaclr in position for raising one of the wheels of an automobile while on its axle. Fig. 2 is a horizontal cross-section taken on section-line 2 2 of Fig. 1. Fig. 3

is an enlarged detail vertical section taken on the section-line 3 3 of Fig. 1.

In the drawings the sectional viewsv are takenlooking in the direction indicated by the little arrows at the ends of the sectionlines, and similar reference characters refer to similar parts throughout the several views.

Referring to the separate parts of my jack as illustrated in the drawings, 1 1 are uprights secured to the base portion 2 and the handle portion 3, all of which constitute the frame of my improved jack. The base portion 2 is provided with the three projecting parts 16 16 16, which gives a wide base and insures stability from toppling over when under the weight of the automobile. The uprights 1 l are of a double angle in cross-section as shown in Fig. 2 and are curved toward eachother at the top, and joined to the handleportion 3, which is for the purpose of lifting and carrying said jack. The legs 15 i15 of the uprights 1 1 serve as guides for the cross-head 4, aswell as to give strength and stiffness to said uprights.

The cross-head 4 is composed of arms 14 extending from either side and are secured to said uprights by means of bolts 12, as shown in Figs. 1 and 2. Holes 18 in the uprights 1 1 allow of vertical adjustment of said cross-head to different sizes of wheels. Cross-head 4 is provided with a sleeve 4, which carries a vertically reciprocating plunger 5, said plunger being provided with the saddle portion 6, upon which the hub of the automobile wheel rests when raised from the lioor. Said saddle is provided with a padding 7 to prevent marring the hub.

A cam 8 is rotatably secured to cross-head 4, by means of the shouldered bolt 10 as shown in Fig. 8. Said cam is provided with a suitable operating lever 9,`and also with stop members 11 and l1', which are adapted to engage the plunger 5 when said cam is rotated to opposite positions, as shown in Fig. l. The lever 9 is curved outwardly as shown in Fig. 2, sufficient to pass the end of the wheel hub when said lever is thrown to its opposite position in raising the wheel.

In the operation of my jack, it is placed close up to the side of the wheel, with the saddle 6 under the hub thereof as shown in Fig. 1. The lever 9 is then thrown over to its opposite position as shown in dotted lines. This rotates the cam 8, which raises the plunger 5, thus raising the wheel as indicated in dotted lines in Fig. 1. It will be noted that when the cam has raised Athe plunger to its extreme limit, that stop l1 engages plunger 5, thus, through the Weight of lever 9, it is securely locked in its raised position and Will not become released until said lever is reversed.

It will be observed that the vertically reciprocating or lifting plunger of my jack does not have an intermittent or step-bystep movement as provided in ordinary lifting acks, but is actuated through its entire movement by one operation of the lever and cam, or other suitable mechanism Which might be provided for actuating said lifting plunger. This is of great importance, for once the jack is adjusted to the size of wheels of an automobile it is always ready for use, so that all that is necessary to do is to place the acl( under the Wheel and thror the lever over to its opposite position when it becomes securely locked, Without the aid of detents or other similar locling devices. It Will also be noted that in the construction of my jack, in adapting the lever to be actuated parallel to the side of the Wheel that I am able to economize in room in storing automobiles in a garage as they can be placed very close together, Which is considered a very important feature by garage men.

I desire to state that While I have shown my improved jack in its most approved form of construction, I am aware that it may be greatly varied in details Without departing from the essential features of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is.

l. In an automobile storage jack, the combination of a base having three projecting members; double angle upright-s projecting therefrom and curved at top t-o engage a suitable handle; a cross-head having arms adapted to b-e adjustably secured to said uprights by means of bolts; a vertically reciprocating plunger provided with a saddle, said saddle being provided With a pad to prevent marring the hub, said plunger operating in a sleeve secured to said crosshead; a cam rotatively secured to said crosshead beneath said plunger and adapted to raise said plunger when said cam is rotated; limiting stops secured to said cam and adapted to engage opposite sides of said plunger to limit the movement of said cam and retain it in either its up or down position, and a lever secured to said cam in such a position that its Weight locks and holds said cam in either its normal or raised posit-ion, substantially as shown and specified.
